Descriptions

In the Linux kernel through 5.4.6, there is a NULL pointer dereference in drivers/scsi/libsas/sas_discover.c because of mishandling of port disconnection during discovery, related to a PHY down race condition, aka CID-f70267f379b5.

En el kernel de Linux versiones hasta 5.4.6, se presenta una desreferencia del puntero NULL en el archivo drivers/scsi/libsas/sas_discover.c debido a un manejo inapropiado de la desconexión del puerto durante la detección, relacionado con una condición de carrera baja PHY, también se conoce como CID-f70267f379b5.
